The first 6 years of life are the most important for language aquisition in both deaf and hearing children. Becoming proficient and fluent with ASL is a difficult task, (as I imagine that you are learning), now combine that with daily life and raising a deaf child.
ASL is an effective communication tool, it does not, imho, lead to English literacy. English, along with hundred of other languages, is based on phoneme, vowel and constant combinations. A deaf child should be given the opportunity to learn English intrinsically and phonetically. This can/does enable them to be on an equal learning field with their hearing peers. There is only one system that teaches a deaf child English phonemically and that is Cued Speech. Literacy is a HUGE issue for deaf children, although cochlear implants combined with auditory verbal approaches will undoubtedly impact the statistics.
You come across to me that you are in the early stages of a never ending curve, and naivety appears to be clouding your vision. I suggest you take a REAL look at the world of deafness and realise the power of the romantic realtionship that hearing people develop with ASL.
